The PlanetQuest Observing Cards are designed to give telescope operators and other interpreters a new way of explaining the night sky. Relating common observing objects to our search for exoplanets makes these spectacular sights more understandable....(View More) These cards are a great resource for use at observing night events, providing new stories to tell about commonly viewed celestial objects.(View Less)

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and...(View More) eventual death. Students discuss the physical concept of equilibrium as a balancing of forces and observe an experiment to demonstrate what happens to a soda can when the interior and exterior forces are not in equilibrium. An analogy is made between this experiment and core collapse in stars, to show the importance of maintaining equilibrium in stars. Finally, students participate in an activity which demonstrates how mass is ejected from a collapsed star in a supernova explosion, thereby dispersing heavier elements throughout the Universe. This activity is part of a series that has been designed specifically for use with Girl Scouts, but the activities can be used in other settings. Most of the materials are inexpensive or easily found. It is recommended that a leader with astronomy knowledge lead the activities, or at least be available to answer questions, whenever possible.(View Less)

In this lesson, students will be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and...(View More) the speeds of galaxies in the universe. Requires some special equipment for spectral analysis and a darkened room for viewing spectra. Suggestions are included for introducing the Doppler Effect for students unfamiliar with this concept. This activity is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1929 Cosmic Times Poster.(View Less)

This lesson uses a simple discrepant event to demonstrate the underlying cause for early miscalculation of the size of the Milky Way galaxy. By standardizing the Cepheid period-luminosity relationship without recognizing there were two types of...(View More) Cepheid variable stars with intrinsic differences in absolute magnitude, a distance calculation error occurred. Requires two lamps and two soft-white light bulbs: 25 watt and 60 watt (estimated materials cost is for light bulbs). This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1955 Cosmic Times Poster.(View Less)

In this lesson, students will investigate the Doppler Effect and discover how the same principle can be used to identify a possible tornado in storm clouds and investigate the rotation of distant galaxies. Students should be familiar with the...(View More) electromagnetic spectrum and the concept of Doppler Shift (links to background information are provided). Materials required for every group of 2-4 students include: a Slinky toy, safety glasses, meter stick, and colored pencils. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1965 Cosmic Times Poster.(View Less)

This activity includes twelve monthly star charts to identify the stars that are visible in the night sky and that are known to have planets around them. The star maps can be used to find constellations and identify stars with extrasolar planets....(View More) (Northern Hemisphere only, naked eye)(View Less)

This toolkit includes PowerPoints and scripts, videos and accompanying activities and handouts about supernovae. Following are specific items in the kit: Supernova in the Lives of Stars PowerPoint and Script; Let's Make a Supernova (participants...(View More) imagine themselves inside a large star at the end of its life, just as it is about to go supernova); Nuclear Fusion (a simple and engaging activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model); Supernova Star Maps (allow visitors to experience finding stars in the night sky that will eventually go supernova); A Universe Without Supernovae (an active game to illustrate the value of supernovae in the universe); and Lives of Stars (an activity and handout about the lifecycle of stars and when supernovae happen.)(View Less)

This activity introduces students to the visible light spectrum, and demonstrates what happens to the appearance of an image when certain wavelengths of light are blocked by filters or made visible using special tools. Students are lead through...(View More) experiments with light and filters, demonstrating that the broader the range of the electromagnetic spectrum we can detect, the more information we gather about the universe. By completing this activity, students gain background information that is necessary for activities that follow this one. This activity is part of the "Cosmic Questions: Our Place in Space and Time" educator's guide that was developed to support the Cosmic Questions exhibit. Activities in the guide can be used in conjunction with, or independently of, the exhibt.(View Less)

This manual provides an overview of how telescopes have changed our understanding of the universe and contains simple demonstrations to use at star parties to get across basic ideas of optics. This manual will also help explain why the images that...(View More) folks see at the eyepiece of a telescope at an outreach star party is so different from images published in magazines. The manual was produced to accompany an outreach toolkit developed for the NASA Night Sky Network. The toolkit is no longer being manufactured, but the activities are available through the manual, which can be freely downloaded.(View Less)
